great to hear!
by the way, the -68 degree reading is a false reading, because that
sensor is not powered since that radio is off. The other one is ok,
reading the PA temperature of the active radio, which starts out at
approx 5 degrees after switch on, and stabilizes at these "high"
temperatures once the craft is close to eclipse when over your part of
the world hi.
You may want to look at the Thin Film Solar Cell payload IV (current
vs voltage) curves by going to options --> show IV curves, since this
payload also includes temperature sensors, on the end of each solar
panel. Temperatures here show quite some extremes from time to time.
These IV curves and temperatures will however only be shown when at
least one of the MEBO's (Measurement Boards) shows supply current
other than 0 in the MEBO fields in RASCAL (meaning that it is on), and
when the satellite's attitude is such that the cells are illuminated.
